Seven years ago, mankind blew up an asteroid approaching Earth, but then faced the consequences - some of Earth's inhabitants mutated into giant monsters. A year later, the Earth's population was reduced by 95%. Joel's parents died, and since then he has been living in an underground bunker in the company of similar survivors. Recently he caught a radio signal from another colony, where his teenage love Aimee lives, and now he's determined to get to her. And it will not be easy, because Joel has no survival skills, and moreover - at the sight of monsters he falls into a stupor.
